John Logie Baird 1888 - 1946
Born in Helensburgh, Baird was a student of electrical engineering. Inventor of the world's first practical, publicly demonstrated television system in 1926, and also the world's first fully electronic colour television tube, demonstrated in 1928.
Alexander Graham Bell 1847 - 1922
Born in South Charlotte Street in Edinburgh's New Town, he emigrated to the United States due to ill health. He initially planned to invent a machine to help the deaf to hear. It was during the course of this research in Boston that he developed the telephone.
James Clerk-Maxwell 1831 - 1879
Son of a Dumfries landowner, Clark-Maxwell is often called one of the world's greatest physicists. He demonstrated that electric and magnetic fields travel through space in the form of waves and at the constant speed of light. This theory predicted the existence of radio waves and was integral in the development of technology that we now take for granted, such as radio, TV and mobile phones.
Sir James Dewar 1842 - 1923
Dewar was born in Kincardine. He invented the vacuum flask whilst investigating the behaviour of gasses at low temperature. He is also credited with inventing cordite.
John Dunlop 1840 - 1921
Dunlop was born in Ayrshire and became a vet. It was his hobby as a cyclist that led him to change the tyres of a bicycle from solid rubber to having a pneumatic tyre. This development was fundamental in the development of the motor car.

Sir Charles Lyell 1797 - 1875
Sir Charles Lyell was born at Kinnordy House near Kirriemuir. He was a distinguished geologist and a great encouragement to Charles Darwin when he was laying the groundwork of evolutionary biology. In 1829, the first volume of his work Principals of Geology was published causing great controversy. The confliction between with science and religious faith was something he felt throughout his life.
John 'Tar' MacAdam 1736 - 1836

John Muir 1838 - 1914

John Napier 1550 - 1617
Napier was born in Merchiston Castle in Edinburgh, which is now part of the university named after him. He was an eminent mathematician and theorised the concept of logarithms. He also invented war machines including the forerunners of the armoured tank and the submarine. He also built Lauriston Castle in Edinburgh, which is now open to the public.
James Watt 1736 - 1819
Born in Greenock, Watt followed his father's trade of mathematical instrument maker. He patented an invention which was the prototype steam engine in 1769, whilst working at an ironworks in Falkirk and worked on further improving this in Birmingham. The unit of electrical power named after him was standardised in the 1880s.
